There were people on set of the giant 'Game of Thrones' battle just showering people with mud and blood

"Battle of the Bastards" made television history on June 19 with
one of the most visceral war scenes ever aired on "Game of
Thrones." Photographer Helen Sloan was among
the enormous team on set for 25 days, filming bloody sequence
after bloody sequence.

Tech Insider caught up with Sloan to get a sense for
what it was like to be on set. One of the coolest tidbits she
shared was the technique used by crew members to make
sure the actors were realistically dirtied up.

"[There are] these special little handheld cannons that the
props and special effects guys have, and they were full of mud
and blood," Sloan explained. "So as everyone's dancing around
trying to stay behind the cameras, these guys are firing off
these mini explosions."

No wonder Kit Harington (Jon Snow) was completely covered
in gore by the end of that fight scene.

"You come out of the shot — they shout 'Cut!' — and you just
look at everyone and everyone's literally splattered," Sloan
said. "We look like we've been massacred."

Thankfully, no one was actually injured during the making of the
battle, despite the insane stunts and logistics involved. For a
